In an interview with Gamespot, Marketing Vice President of Bethesda Pete Hines revealed some information about Fallout 4’s new base customization. He explained that players will get to decide many different aspects and not just pre-determined frameworks. Hines said…

“It’s not just, ‘Hey, here’s Breezehome [one of the houses in Skyrim],’ where we just picked a house, and you can buy it, and you can go to somebody and say, ‘Here’s this much gold, and put this thing into my house.’ [In Fallout 4] it’s, ‘Now I’m building it, I’m actually building the house, I’m building the wall, I’m placing the door, I made the table, I made the mattress.’ It’s that sense of making your own way in the world and defining, ‘Who am I and where do I live and what’s my story in this world?'”

He later went on to explain that even though building locations are limited, you will still have lots of options for building within the spaces you are given. saying…

“There are preset locations around the world where you can [build]. You can definitely build up… [In one demo] there’s a radio tower, and the developer that built it just kept going up and incorporating the tower into their structure. Much like a game like Minecraft, you can be a noob and just build a simple little thing. And you can also get the guys who go crazy and [can say], ‘I rebuilt the spaceship from this game… [or] I rebuilt the Tardis from Doctor Who using the lights and stuff and it looks exactly like it.’ Like, holy s**t that’s incredible.”
